Eir Partners

What Eir Partners does

Eir Partners Capital, LLC is a Miami-based middle-market private equity firm founded in 2015 by Brett Carlson (formerly a principal at Great Point Partners and CEO of iVantage Health Analytics) that invests exclusively in healthcare technology and tech-enabled services. The firm operates three flagship investment funds: Program I ($255M, closed 2021), Investment Program II ($496M, closed May 2024), and Eir Partners III ($1B, closed January 2026), with cumulative capital commitments of approximately $1.8B and $5.5B+ in completed or partnered healthcare technology transactions across 14 platform investments and 50 total transactions. Eir's investment approach pairs an Eir Deal Partner (responsible for strategic direction and capital stewardship) with an Eir Operating Partner embedded in execution, supported by a bench of 20+ senior operating executives, and follows a proprietary bottoms-up thematic sourcing model focused on four verticals: payor services & technology, pharma services & technology, provider payments & technology, and B2B healthcare technology.

Eir Partners generates revenue through conventional private equity fund economics: management fees on committed/invested capital across its three funds (equity check sizes $25M-$125M+), transaction and monitoring fees, and potential carried interest on realized exits. Notable realized exits include the $3.2B sale of Equian to UnitedHealth/Optum (June 2019) and the sale of Convey Health Solutions to TPG (September 2019), both in collaboration with New Mountain Capital as a long-standing co-investment partner. Active portfolio includes majority-owned healthcare tech companies such as AgentAI (RCM AI platform), Gifthealth (digital pharmacy), Helpware (digital customer experience with 2,500+ employees), Machinify (healthcare intelligence), PharmaForceIQ (pharma omnichannel), Porter (AI care coordination), QuartzBio (biomarker intelligence), ReviveHealth (virtual care), Smarter Technologies ($800M+ revenue AI healthcare automation platform formed by Eir/New Mountain in May 2025), Long Tail (AI-native utilization management), ClaimLogiq, Capta Health Partners, Millennia Patient Services, and others. The firm's GTM channels comprise direct proprietary sourcing of founders/management teams, co-investment channel partnerships (notably with New Mountain Capital and Transformation Capital), and limited partner capital raising with Lazard Frères & Co. serving as placement advisor on Fund II.

Core offering

Eir Partners is a middle-market private equity firm that invests exclusively in healthcare technology and tech-enabled services companies through three flagship funds (Program I, Program II, and Fund III). The firm provides growth equity through control buyouts with equity checks ranging from $25 million to $125 million, applying an operator-led partnership model in which each investment is co-led by a Deal Partner and an embedded Operating Partner across finance, technology, go-to-market, human capital, and M&A functions.

Product overview

Eir Partners Capital is a Miami-based private equity firm that exclusively invests in healthcare technology and tech-enabled services through three primary investment programs: the inaugural Eir Partners Investment Program I ($255M, closed 2021), Eir Partners Investment Program II ($496M, closed May 2024), and Eir Partners Capital Fund III ($1B, closed January 2026). Rather than a single unified software product, Eir Partners operates a platform-plus-modules-style investment architecture where each fund is a discrete capital vehicle, and the underlying portfolio of health tech companies (such as AgentAI, Capta Health Partners, Caryn Health, FitOn, Focus, Gifthealth, Helpware, Machinify, PharmaForceIQ, Porter, ReviveHealth, Smarter Technologies, QuartzBio, and Long Tail) collectively represents the firm's deployed product across four focus areas: payor services & technology, pharma services & technology, provider payments & technology, and B2B healthcare technology. The Operator-Led Partnership Model is the firm's core value-creation service applied across all portfolio companies, pairing a Deal Partner with an embedded Operating Partner.
